Explanation

Discarding temporary physical memory can reduce the physical memory reported in use by the Java™ application. The physical memory that is released is available to other processes without the operating system needing to search for the least recently used frames.

The -XX:-DisclaimJitScratch option turns off a previously enabled -XX:+DisclaimJitScratch option.
